Significant Figures – 100 examples

Flashcards focusing on whether trailing zeros in 100 are significant depending on the presence of a decimal point.

100 without a decimal point

Only one significant figure (the '1'); the trailing zeros are not significant.

100. with a decimal point

Zeros to the right of the decimal point are significant; 100. has three significant figures.

Rule about decimal points and trailing zeros

If a decimal point is present, trailing zeros are significant; if not, trailing zeros are not significant.

Significant figures (general concept)

Digits that carry meaning about the precision of a measurement; trailing zeros are significant only when a decimal point is shown.
